How to set position in image in canvas in Fabric js?

Answer 1

context.drawImage(img,sx,sy,swidth,sheight,x,y,width,height);

this is in native JS

• img Specifies the image, canvas, or video element to use
  
• sx Optional. The x coordinate where to start clipping
  
• sy Optional. The y coordinate where to start clipping
  
• swidth Optional. The width of the clipped image
  
• sheight Optional. The height of the clipped image
  
• x The x coordinate where to place the image on the canvas
  
• y The y coordinate where to place the image on the canvas
  
• width Optional. The width of the image to use (stretch or reduce the image)
  
• height Optional. The height of the image to use (stretch or reduce the image)
  

in fabric:

var canvas = new fabric.Canvas('canvas', { selection: false });
    fabric.Image.fromURL("http://timeplusq.com/dakshin/clip03.png", function(obj) {
    canvas.add(obj.set({
        width: 294,
        hasControls: false,
        //cornerColor: 'green',cornerSize: 16,transparentCorners: false,
        selection: false,       
        lockRotation:false,
        //lockMovement: false,lockMovementY: false,lockMovementX: false,
        //lockUniScaling: false,lockScalingY:false, lockScalingX:false,
        hoverCursor: 'default',
        hasRotatingPoint: false,
        hasBorders: true,borderColor: 'red',borderSize: 2,
        transparentBorder: false,
        height: 294,
        angle: 0,
        cornersize: 10,
        left: 2, 
        top: 2
    }));
    canvas.setActiveObject(canvas.item(0));
    canvas.item(0).selectable = false;
    canvas.backgroundColor = 'rgba(0,0,255,0.3)';
    //img.bringToFront();
    canvas.renderAll();
    });
